The Humane Society of the United States is the nation’s largest and most effective animal protection organization. We and our affiliates provide hands-on care and services to more than 100,000 animals each year, and we professionalize the field through education and training for local organizations. We are the leading animal advocacy organization, seeking a humane world for people and animals alike. We are driving transformational change in the U.S. and around the world by combating large-scale cruelties such as puppy mills, animal fighting, factory farming, seal slaughter, horse cruelty, captive hunts and the wildlife trade.
